The collagen fiber network of the ECM is a major contributor to the passive force,55 in addition to its role in force transmission during contraction.56,57 Due to its structural arrangement in close relation with muscle fibers, the determination of the mechanical properties of ECM is extremely difficult.	cache/bam-8982.pdf	txt/bam-8982.txt
